1. Field of the Invention
The present invention relates to an air filter device for an air exhauster. Particularly, the present invention relates to the air filter device having at least one static electricity dust-collecting module and at least one water-cleaning module, thereby employing static electricity and water synchronously for increasing air-filtering efficiency of the air filter device.
2. Description of the Related Art
Taiwanese Patent Publication No. 421254, entitled “static electricity range hood for modular kitchenware,” discloses a static electricity range hood including a static electricity dust-collecting module and a casing. The static electricity dust-collecting module has an ionizer portion and a dust-collecting portion. The ionizer portion and the dust-collecting portion are mounted on a rack which further forms a plurality of electrode plates. Each end of the combination of the ionizer portion and the dust-collecting portion is provided with a filtering net. An inside of the casing is provided with a pair of slide tracks for receiving the static electricity dust-collecting module. The static electricity range hood employs the static electricity dust-collecting module for providing a static electricity filtering effect. Disadvantageously, the static electricity dust-collecting module, after long-term use, may be faced with greasy dirt which cannot be automatically cleaned and thus must be manually washed.
Another Taiwanese Patent Publication No. 398607, entitled “laterally cleaning sprayer for static electricity range hood,” discloses a static electricity range hood including a static electricity dust-collecting module and a casing. The static electricity range hood further includes a water sprayer disposed between an air inlet and the static electricity dust-collecting module. Greasy dirt and dust may accumulate on the static electricity dust-collecting module after long-term use, which may affect exhaust air of the static electricity range hood. Once occurred, the static electricity range hood must be stopped in operation for removing the accumulated greasy dirt and dust. In cleaning operation, a supply valve is turned on to supply water to the water sprayer which has spouts for laterally spraying water on static electricity dust-collecting module. Although the water sprayer can clean and remove the greasy dirt and dust accumulated on the static electricity dust-collecting module, water may affect efficiency for generating electrostatic charges in filtering greasy dirt and dust. Consequently, static-generating operation of the static electricity dust-collecting module and water-cleaning operation of the water sprayer cannot be synchronous, that is to say, disadvantageously, water sprayed from the water sprayer cannot be used to cool or filter greasy dirt and dust synchronously during operating the static electricity dust-collecting module. In other words, the water sprayer can only clean the greasy dirt and dust accumulated on the static electricity dust-collecting module, but it cannot directly cool and filter greasy dirt and dust for increasing efficiency in filtering greasy dirt and dust when exhausting air. Hence, there is a need for improving the static electricity dust-collecting module.
The present invention intends to provide an air filter device for an air exhauster, having at least one static electricity dust-collecting module and at least one water-cleaning module. The static electricity dust-collecting module and the water-cleaning module can employ static electricity and water synchronously for double-filtering greasy dirt and dust when exhausting air. Accordingly, the air filter device may increase efficiency for filtering.
The primary objective of this invention is to provide an air filter device for an air exhauster, wherein having at least one static electricity dust-collecting module and at least one water-cleaning module. The static electricity dust-collecting module and the water-cleaning module employ static electricity and water synchronously for filtering greasy dirt and dust so as to increase filtering efficiency.
The secondary objective of this invention is to provide the air filter device for the air exhauster, wherein separately arranging at least one static electricity dust-collecting module and at least one water-cleaning module. Such an arrangement permits conveniently disassembling or reassembling the static electricity dust-collecting module and the water-cleaning module in need of repairing or cleaning.
The air filter device in accordance with the present invention includes at least one static electricity dust-collecting module, at least one water-cleaning module and a casing. The static electricity dust-collecting module is operated to generate static electricity for electrically attracting greasy dirt and dust filled in exhaust air. The water-cleaning module mechanically connects to at least one side of the static electricity dust-collecting module, and includes a plurality of guiding members each forming a longitudinal groove for guiding water in wetting and washing greasy dirt and dust filled in exhaust air.

The water supply trough 23 contains water output from the water conduit 24 for running through the guiding members 22. The water supply trough 23 provides with a series of water-dripping holes 231 at its bottom plate. In the first embodiment, the water-dripping holes 231 are corresponding to an inner surface of the longitudinal groove 221 of each of the guiding members 22. Connected between the water supply trough 23 and the water-collecting reservoir 25 is the water conduit 24.
The water-collecting reservoir 25 is used to collect water draining from the water-dripping holes 231 of the water supply trough 23. The water-collecting reservoir 25 includes a water pump 251, a water-level detecting switch 252 and a wastewater outlet 253. In the first embodiment, the water-level detecting switch 252 is preferably a float ball switch for detecting water level in the water-collecting reservoir 25 so as to turn on or off the water pump 251 which can pump water into the water supply trough 23. Furthermore, the water-level detecting switch 252 can decide to refill the water-collecting reservoir 25 if water level in the water-collecting reservoir 25 becomes lower than a predetermined position. Preferably, the wastewater outlet 253 is located at a relative height of the water-collecting reservoir 25 for draining wastewater from the water-collecting reservoir 25 that the collected water reservoired in the water-collecting reservoir 25 can be recycled and reused.

In the first embodiment, the casing 4 includes a dust-collecting compartment 41, an air inlet 42, an air outlet 43 and a plurality of slide tracks 44. Disposed either side of the casing 4 is the air inlet 42 and the air outlet 43 which are in communication with the dust-collecting compartment 41. The air inlet 42 connects with the air inlet conduit 40a for inputting exhaust air while the air outlet 43 connects with the air outlet conduit 40b for outputting filtered exhaust air. Preferably, the slide tracks 44 are parallel and extended in the dust-collecting compartment 41 which permits installing the static electricity dust-collecting module 1, the water-cleaning modules 2 and the filtering nets 3 within the dust-collecting compartment 41 of the casing 4.

The exhaust air passed through the guiding member 22 of the water-cleaning modules 2 may be meandered since each of the air passages of the guiding row may be mis-aligned with those of the adjacent guiding row. Such an arrangement results in exhaust air passed through the air passages of one of the guiding row of the water-cleaning modules 2 to be directly guided to the longitudinal groove 221 of the next adjacent guiding row. The water-cleaning module 2 may relatively mitigate a filtering workload of the static electricity dust-collecting module 1 since the water-cleaning module 2 has already filtered and cooled major greasy dirt and dust in firstly filtering operation.

In filtering operation, exhaust air cannot directly pass through the water-cleaning module 2 and meanders in spaces defined between the guiding members 22 and the reverse-guiding members 22′. In the second embodiment, the water-dripping holes 231 of the water supply trough 23 are correspondingly aligned with the longitudinal grooves 221 of the guiding members 22 for dripping water. In an alternative embodiment, the water-dripping holes 231 of the water supply trough 23 may be correspondingly aligned with the longitudinal grooves 221′ of the reverse-guiding members 22′ for dripping water.
